Braunomyces dictyosporus gen. sp. nov. from Vietnam.

The generic name Braunomyces (ascomycetes, asexual morph), with B. dictyosporus as type species, is described, illustrated and discussed, based on material collected in Vietnam on leaf debris of an unidentified broadleaved tree. The new genus is well characterised and quite distinct from other synnematous and non-synnematous dematiaceous hyphomycete genera by its unique combination of traits, viz.

Bartheletia paradoxa is a living fossil on Ginkgo leaf litter with a unique septal structure in the Basidiomycota.

Bartheletia paradoxa, a basidiomycete growing on fallen leaves of Ginkgo biloba, is redescribed. In autumn a rapidly developing anamorph is formed on freshly fallen leaves and subsequently a teleomorph with hemispherical pustules of thick-walled resting spores (teliospores) that germinate after a resting period of one year with stipitate, longitudinally septate, statismosporic phragmobasidia. The basidia produce several basidiospores on each sporogenous locus.
